I have the exact same doubt, only the difference here is that I am upgrading Windows XP Professional to Windows 7 Home Basic or Windows 7 Home Premium.

I am also hunting for prices. Is Windows 7 going to come cheap, especially considering that its recession time and unlike windows vista, windows 7 is just a continuation of previous OS's features and hence less has been spent on its R&D compared to Vista ?

Home Basic seems restricted to "emerging markets" so India is included. Good. But not sure if its available in Retail. Many say its OEM exclusive. Bad.

So Home Premium is the starting OS for retail with support for Multi Touch and Aero, which basic lacks. I am only worried about multitouch and not aero.
